A fundamental principle of color theory in cosmetology is that complementary colors can enhance each other. Complementary colors are pairs of colors that, when combined, cancel each other out, resulting in a grayscale color (like black or white). In practice, this means that using complementary colors can create a dynamic look and improve the overall appearance of a client’s makeup or hair color. For instance, using shades on opposite sides of the color wheel, like blue and orange, can make both colors appear more vibrant and can add depth to the overall look.

Additionally, this principle applies in various combinations, whether in hair dyeing techniques or in makeup applications. By understanding how complementary colors interact, cosmetologists can create visually appealing contrasts that draw the eye and enhance the features of their clients effectively. This principle is crucial for providing well-rounded services that utilize color effectively in hair, makeup, and overall styling.
